Sentinel issue

i have often seen statements written like this :

while(1){} for example...

if the sentinel in the while statement is not a va riable, how is the loop going to end? how are we gonna end the loop?

while(1) will keep on going forever just like
for( ; ; )

you can break; out of the loop

It doesn't. What you have is a infinite loop.

Inside the block a break; is executed to break out of the loop.

This type of while can be used when there is no clear sentinel to exit the loop.
